This invention relates to cash registers, and more particularly toindicating mechanism therefor.

The subject matter of this application constitutes a division of acopending application, Serial No. 451.508, 'filed on March ll, 1921, byB. M. Shipley.

The principal object of this invention is to provide a machine of awell. knowntype with mechanism tor disabling its indicating mechanism toprevent a display of totals or sub-totals.

Mechanism is therefore provided herein for disabling the indicatingmechanism on total The machine to which the invention is shown appliedisof the general type shown and described in Letters Patent oi the UnitedStates No. 1 ,230,864 issued to W. A. Ghryst on June 526, 191?; LettersPatentof the United States. Nos. 1242.170 and 1,39%,256, issued to F. L.Fuller on Oct. 9, 191'? and Oct, 18, 1921, respectively. it is to beunderstood however that this invention, is applicable to many othertypes of machines, and it is therefore not desired to limit its use tothe machineshown herein.

In View of the fact that a very complete description of the machine isgiven in the before-mentioned patents, only a very brief descriptionthereof will be included herein. The keyboard comprises a plurality ofbanks of depressible keys for setting up the amounts to be entered andfor controlling the selection and engagement of the totalizers 26. Anamount bank and differential mechanism are shown in Fig; 1. These keyswhen depressed are adapted to cooperate with a bell. crank 27 carriedbytotalizer actuating Alatch member supported on said bellcrank normallyconnects the actuating n'iember 28 to a driving segment 29. This segmentis given an invariable extent of movement on every operation of themachine by means of pair of cams carried by the main drive shaft 46, ait-shaped member 47 and a link 48., ll of which are well known in theart. When the segment 29 isgiven this invariable movement the or" thedepressed key. vThis moves the latch member 24 to disconnect theactuating member 28 from the segment 29 and to hold the actuating memberin its ad usted positlon as is well known in the art.

When the segment 29 is returned to the position shown in Fig.1, surface30 therei on, engages a pin 31 carried by the actuating member 28 andreturns this member to zero. Before this is accom )lished the selectedto talizers 26 are rocked into engagement with the actuating member thatwhen this member is returned to zero the value represented by thedepressed key will be entered thereon.

Pivoted to the actuating member 28 a beam 32 which is bifurcated tocooperate with a stud carried by a link 34. By means of this beam 32 thedifferential movement of the actuating member 28 is transferred to thelink 34 in a manner fully described in the above referred to patents.

At its lower end the link 34 is pivoted to an arm loose on a rod 36 andfast on a spiral. segment 3'? also carried by said rod. The segmentmeshes with a spiral pinion 38 fast on a shaft 39 supported by laterallyspaced frames. Also fast on the shaft 39 is a segment 4:0 which mesheswith a rack 41 (Fig. 7). This rack also meshes with a pinion 42 fast onthe inner end of a sleeve 43 which at its outer end *arries a similarpinion l4 meshing with a type wheel 45. It can be seen from the abovethat the movement of the differential actuating member 28 will, throughthe train of mechanism just de scribed, move its appropriate type wheela corresponding extent.

There are two groups of indicators (Fig. 1) for each of the amount banksof keys 25. One group of indicators indicates toward the front-of themachine and the other group indicates toward the back of the machine.There are other groups of indicators which are associated with thevarious control banks of keys but as all of these indicators are mountedin a similar manner the group associated with one amount bank only isillustrated and described herein. The group of indicators 55 (Fig. 2)which indicate toward the front of the machine are carried in av casing56 and rest upon a ledge 57 of a plate 58 slidably mounted on rollers 59on rods 60 supported by two plates 61. only one of which is shown. Theplates 61 are secured to the side frames of the machine by studs 62. Theplate 58 has teeth 63 meshing with a segment 64 integral with a segment65 fast on one of a plurality of sleeves 66 supported by a shaft 67. Theupper end of the link 34 is. pivoted to the segment 65 so that thedifferential movement of the differential actuating member 28 istransmitted by means of beam 32 and link 34 to the segment 65 andthereby to the segment 64 and plate 58. In this manner the plate 58carryingthe group of indicators for indicating toward the front of themachine is differentially positioned to bring any desired indicator intooperative relation with an in dicator-lifting means to be hereinafter described.

The indicators 55 which indicate toward the back of the machine aredifferentially positioned by means of a plate similar to plate 58. Asthe indication from the back of the machine is the reverse of thatlookiug from the front, each of the segments 65 is secured to a sleeve(36 so that the move ment im 'iarted to the segment 65 is tl'irough thesleeve 66 imparted to the plate 58 which carries the indicators forindicatin toard. the back of the machine. The front and back indicatorsfor the middle amount bank are carried in casings 56 supported by plates58 integrally connected as shown in Fig. l

[iii/Hay; moo/1 (moon.

After the indicators have been ('llllfi1611- tially positioned accordingto the keys which have been depressed, the selected indicator is exposedto view. This mechanism is substantially the same as that shown and des-ribed in the patent to Fuller No. 1,168,?48 granted Doc. a, l9l5.licfore the indicators 55 can be di'i ercntialiy positioned it isnecessary to lower those exposed during the prc vious operation. A frame70 (Fly. 2), rectangular in shape, has at each end an arm Tl carrying a.roller '72 projecting into a slot 7-3 in each plate 61. The frameTO alsohas projections 71: at the front and back thereof adapted to engage theindicators in a manner fully described and illustrated in said patent. Pvotcd on a stud 75 on the frame '70 is a link T6 also pivoted to a lever7? fast on a shaft 78 mounted in the side frames of the machine. Thereis a link 76 and a lever 7T 2 each end of the machine in order that the:i' ame TO may be lifted evenly to prevent bin Pivoted on a stud 79 onthe lever roller 81. projecting into the short portion of an L-shapedslot 82 in a lever 83 loose on a rod 84; carried by the side frames ofthe machine. The lever 83 has two rollers 85 and 86 cooywwting with.cams 87 and 88 respectivcly, fas" on the shaft The link 80 has a roller89 a; nst. which rests an edge 90 of a pawl 91 loose on a rod carried bythe side frames. A spring 93 holds the pawl 91 against the roller ti!)so that the roller 81 is normally maintained in the short portion of theL-sha ed slot 82.

From the above de-crii tion it ca be clearly seen that when the cams and88 are rotated count er-clockwise the lever 83 is rocked clockwisethereby moving the link 80 downward in the d: cclion of its length androcking the levers Ti and shaft '78. This movement of the levers 7''?through "the links 76 lowers the fra in TO and the indicators which werecxpce L. du -in ay tho operation. As the link 80 is bcin huncreth thespring 93 maintains the tension against the roller 89 so that the rollertil cannot become disei'ie'agcd from the short portion of the slot 82. Astud 9 3i limits the clockwise movement of the pawl 01. After the armusly cxoosed indicators 55 have been lowere h as j st descril'ied, and

after the plates 58 have been differentially positioned to select a newindicator, the cams 87 and 88 rock the lever 83 counter-clockwise tohome position. This raises the link and consequently rocks the levers 77counterclockwise to home position, thereby raising the links 76 to raisethe frame 70, whereby the projections 74: thereof engage the selectedindicators 55 and expose them to View;

After the frameis in its lowerposition it is held locked in thisposition until the plates 58 have been differentially positioned toselect a new indicator. This locking means will now be described.Slidably mounted on the rods 60 is a plate (Fig. 2), having a slot 96engaged by a pin 97 on a lever 98 on a shaft 99 supported by the sideframes. Pivoted tothe lever 98 is a link 100 (Fig. 4) which is pivotedto a lever 101 (Fig. looseon the stud 84:. The lever 101 has rollers 102and 103 cooperating with cams 104 and 105 respectively fast on the shaft16. The cams 10% and 105 are so timed that after the frame it) has beenlowered said cams rock the lever 101 clockwise, which, through the link100, rocks the lever 98 counter-clockwiseand moves the plate 95 towardthe left, whereupon a. projection 106 thereof engages the roller 72 onthe arm 71, thereby holding the frame 70 in its lowered position untilthe indicators 55 have been selected, after which the counter-clockwisemovement of the lever 101 to normal position rocks the lever 98clockwise to disengage the projection 106 from the stud 72 therebyallowing the frame 70 to be raised to expose the selected indicators toview.

Alibi 22g mechanism.

Each of the segments 65 has aiming notches therein with which ana-lining bar 107 cooperates. This alining bar 107 is in tegral with.parallel arms 108 2 and at) fast on the shaft 99. as above described.The lever 98 is fast on the shai 90. Therefore when said lever is rocked'cotmter-clockwise the shaft 99 rocks the arms108 counter-clockwise anddisengages the alining bar 107 from the notch in the segment 65 so thatthis segment may be differentially positioned under the control of thedirerential r echanism. 'lVhen the lever-98 is rocked clockwise tonormal position the aliner 107 is again engaged with a notch on thesegment 65 to hold the segment in proper position until a subsequentoperation of the machine.

Thereis also another alining mechanism 109 which directly alines theplates 58. This aliner 109 is in the form of an angle iron (Figs. 2, 3and 4). in alinement with each plate 58 the aliner 109 has slot 110 andalso an alinin tooth 111 which cooperates with notches 112 in. the plate58. The

aliner 109 is secured at each end to horizontal portions of levers 113pivoted on studs 11% mounted in the plates 61.

Pivoted to the levers 113 are links 115 which are also pivoted to thelevers 98. When said levers are rocked counter-clockwise, as previouslydescribed, the links 11: rock the levers 113 clockwise and disengaget'le alining teeth 111 from the notches 112 of the plates 58. The slots110 of the aliner 109 then act as a guidefor the p 58 to hold them inproper late :11 position. Amer the desired indicaters have beenselectedand before the frame 70 is raised to expose the selectedindicators to View, the levers 98 are rocked clockwise to home position,which movement through the links 115 rocks the levers 113counter-clockwise, whereby the teeth 1 11 again engage the notches 112and hold the indicators in proper alinem-ent until the ma chine is againoperated.

Indicator crippling on. totalizing operations.

of this link are bifurcated to surround the rod 92 and the shaft 11'2".The link 129 carries a roller 130 adapted to cooperate with a. surface131 of the previously described link 80.

It is well known in the art that machines of this type are controlled ontotal and subtotal priiitinr;- operations by means of a total lever 1356). Movement of the total lever either up or down, out of itsaddingposition, rocks the sl aft 11'? clockwise, to lock out the amountkeys and certain banks of control keys, and to control the machine for atwo cycle operation as vell known in the art. This movement isaccomplished in the following manner: integral with the total lever 25is 5 plate 136. A pivoted lever 138 cc ries a roller cooperating with aslot 13? formed in this plate. Also pivoted on the same center the lever138 is a member 1.39 which has a'slot formed therein into which projectsa roller carried by an arm 1 .210 on shaft 117. The lever 138 and member139 connect-ed together by a spring 1 11 and a pin and slot connection.it can be seen from the above that when the total lever moved out of itsadding position, the lever will be rocked counterclockwise due to theshape of the slot 137. This movement of the lever 138, through thespring 1 11, ,ocks the me. her 139 also counter-clockwise. which will.in turn, rock the arm 14:0 and shaft 11'? clockwise.

Upon this movement of the shaft 117 the rm 118 will be rockedcounter-cloclnvise as seen in 2. This n'iovement of the arm 118, throughthe engagement of the pin 119 with the slot 120, moves the link 129 tothe left. This positions the roller 130 into cooperative relation withthe surface 131 of the link 80.

During adding operations it will be remembered that the link 80 is moveddownward by the lever 83 at the beginning of the operation to lower theindicators which were exposed (hiring the last previous operation.During the first part of the movement of the shaft 16 (Fig. 2) the lever83 is rocked clockwise and lowers the link S0, which lowers thepreviously exposed indicators to their normal positions. As the link 80nears the end of its downward movement. during a total or sub-totalprinting operation the surface 131 engages the roller 130 which has beenmoved to the left by movement of the total lever, and rocks the link 80clockwise about the stud 79 thereby disengaging the roller 81 from theshort portion of the L-shaped slot and positioning it in the end of thelong portion of said slot. Then, when the lever 83 is movedconnter-clockwise, to home. position, it has no etl'ectupon the link 80,and. consequently the indicator lifting frame is not raised to exposeselected indicators to view. During the second rotation of the shaft 16the lever 83 is again rocked clockwise, thereby positioning the shortportion of the slot 82 opposite the roller The lever 83 is then againrocked counter-clockwise to home position without lifting the link 80.The total or sub-total printing operation is now completed with theroller 81 near the bottom of the long portion of the slot 82. During atotal or sub-total printing operation, whichever the case may be, theshaft 117 is rocked still farther in a counter-clockwise direction, bymechanism not shown herein but disclosed in the patents referred to. Asthe lower portion of the slot 120 is concentric with the shaft 117 thelink 129 receives no farther movement to the left than that which wasgiven it by the first conntcr-clockwise movement of the shaft 117 underthe direct control of the total lever 135.

When the total lever is again moved to its adding position it rocks theshaft 117 to home position, thereby rocking the arm 11S clockwise, whichmoves the link 129 to the right to the position shown. As the machine isnow operated and the short portion of the slot 82 positioned oppositethe roller 81, the s nking 93 through the engagement of the surface 90of the pawl 91 with the roller 89 will rock the link 80connter-clockwise thereby mo ing the roller 81 into the short portion ofthe slot 82. \Vith the roller in this position, the counter-clockwisefi'lOVGHlGnt of the lever 83 to home position raises the link 80, rocksthe arm 77 counter-clockwise and raises the link 7 6 to expose theselected indicators, for this operation, to View.
